One-time forming construction method for single-pile foundation of cast-in-place piles in electric transmission line engineering

The invention discloses a one-time forming construction method for the single-pile foundation of cast-in-place piles in the electric transmission line engineering. The one-time forming construction method is characterized by comprising the following steps that 1) the positions on which the cast-in-place piles are planned to be cast are confirmed, and sub-pits are positioned; 2) grooving is carriedout on the positioned sub-pits to form holes; 3) slag suction and hole cleaning are carried out in the holes; 4) prefabricated reinforcement cages are installed in the holes; 5) guide pipes are embedded in the holes and the reinforcement cages; and 6) when the hole formed in the step 4) is a single-pile hole, detection and acceptance can be carried out after concrete is poured into the hole and curing is carried out, and when the holes formed in the step 4) are a plurality of single-pile holes in parallel, after the concrete is poured into each hole and curing is carried out, cleaning and detection are carried out on
